The understanding of neutrino nucleus interaction cross-sections is a dominant uncertainty for current neutrino oscillation experiments. Reductions in these uncertainties will be essential for future experiments. Detectors with low thresholds, such as a high pressure TPC (HPTPC), allow models to be compared in new regions of parameter space and as such for uncertainties to be reduced. A proto-type ... More

One of the primary challenges in current and future precision neutrino oscillation measurements is understanding nuclear effects in neutrino-nucleus interactions. Current models are known to be deficient in a number of areas, leading to relatively large uncertainties which will become limiting soon. MicroBooNE is a liquid argon TPC in the booster neutrino beam at Fermilab, which has the ability to ... More

As neutrino oscillation experiments continue to improve their sensitivity, it is increasingly important to understand and constrain the details of neutrino interactions with complex nuclei. As part of this drive comes the desire to measure single pion production mechanisms, which can provide particular insight into the cross sections for neutrino interactions that induce baryon resonances and cohe ...

Liquid Argon Time Projection Chambers (LArTPCs) are sensitive to low energy electron neutrinos via a charged current interaction on argon. The Deep Underground Neutrino Experiment’s (DUNE’s) 40kt far detector at the Homestake mine in South Dakota will therefore offer a unique opportunity to study supernova neutrinos. The detection of galactic supernova burst neutrinos, a primary physics goal o ... More

The predictions of the cosmogenic-neutrino flux at 1e9 GeV are pretty solid and depend mostly on the composition of the cosmic-rays above 1e10 GeV. It is, therefore, no surprise that the hunt to detect the first cosmogenic neutrino is a hot topic in astroparticle physics. But pushing the experimental sensitivity into the predicted flux region is a challenge. A major obstacle for experiments is to ... More

Neutrinos in the cosmic ray flux with energies above 100 PeV are detectable with the Surface Detector array (SD) of the Pierre Auger Observatory. Neutrino identification is efficiently done for neutrinos of all flavors interacting in the atmosphere at large zenith angles, as well as for Earth-skimming tau neutrinos. No neutrino candidates were found up to 31 Mar 2017, and this allowed to constrai ... More

A combined analysis of disappearance and appearance data of NOvA experiment gives three nearly degenerate solutions. This degeneracy can be understood by the following argument: We first consider $\nu_e$ appearance signal due to vacuum oscillations in the limit of maximal $\theta_{23}$ and no CP-violation. We then calculate the deviations induced in the signal event rate by (a) matter ef ... More

I report the results of a search for $\bar{\nu}_{\mu} \rightarrow \bar{\nu}_{e}$ oscillations at the T2K experiment in a 3-flavour framework using an exposure of $1.49 \times 10^{21}$ Protons On Target (POT) in $\nu$ mode and $1.12 \times 10^{21}$ POT in $\bar{\nu}$ mode, an increase of $50\%$ in the $\bar{\nu}$ exposure compared to results reported in 2016. Results are reported for a joint ana ... More

MicroBooNE is a 90 ton fiducial volume Liquid Argon TPC (LArTPC) neutrino experiment on the Booster Neutrino Beamline at the Fermi National Accelerator Laboratory. One of MicroBooNE’s primary physics goal is to investigate the excess of $\nu_e$ seen by MiniBooNE in the [200-600] MeV range. MicroBooNE will constrain the excess of $\nu_e$ from their expected intrinsic component in the beam by usin ... More

On 22nd September, 2017 a high energy neutrino event was detected by the IceCube neutrino detector in spatial coincidence to the blazar TXS0506+056, which was also observed by the Fermi-LAT satellite to be in a state of enhanced gamma-ray activity. These observations triggered a series of multi-messenger and multi-wavelength (MWL) campaigns. On 24th September 2017, the MAGIC telescopes started fo ... More

We show that neutral current (NC) measurements at neutrino detectors can play a valuable role in the search for new physics. Such measurements have certain intrinsic features and advantages that can fruitfully be combined with the usual well-studied charged lepton detection channels in order to probe the presence of new interactions or new light states. NC measurements provide access to different ... More
